Hi all https://github.com/apache/pulsar/pull/20659 introduced the class `jdk.internal.platform.Container`, but this class was introduced by JDK-11. So after this PR, `branch-2.10` of Pulsar did not support `JDK-1.8` anymore.
But our doc-side https://pulsar.apache.org/docs/2.10.x/getting-started-standalone/#system-requirements said that the Pulsar release `2.10.x` can be started with `JDK-1.8`. So I want to revert the PR https://github.com/apache/pulsar/pull/20659. Thanks Yubiao Feng
